Overview

Replace Actor lets you seamlessly swap the subject in an existing video with a new character—without rebuilding the video from scratch.

This feature is ideal for reusing winning creatives while adapting them to different audiences, markets, or branding needs.

What Is Replace Actor?

Replace Actor is a tool within Arcads that allows you to replace the main character in a video while preserving:

  • the original scene

  • camera movement

  • timing and pacing

  • overall visual structure

  • Script and voice

You simply provide a video template and an image of the new character, and Arcads handles the transformation.

👇 How to Use Replace Actor

  1. Select Replace Actor from the tool list

  2. Upload a video template

    • Accepted format: .mp4

    • Maximum size: 150 MB

  3. Upload an image of the character to replace the original actor

    • Accepted formats: .jpg, .png

    • Maximum size: 50 MB

  4. Generate — Arcads will automatically replace the actor in the video

Best Practices

  • Use a clear, front-facing image of the replacement character

  • Ensure the face is well-lit and not obstructed

  • Avoid extreme angles or heavy motion in the source video

  • Videos with a clearly visible subject deliver the best results
